housing to be flavored by the material before passing out of the mouthpiece assembly for inhalation by the user; wherein the first housing and the second housing are connected together to form the mouthpiece assembly and the mouthpiece assembly is configured to be releasably connectable to a section of the aerosol provision device from which the aerosol generated by the aerosol provision device enters the mouthpiece assembly; and wherein the mouthpiece assembly is configured to be releasably connected to the section of the aerosol provision device via a push fit connection, and wherein the second housing is configured to be received in a recess in the section of the aerosol provision device and an outer circumferential surface of the second housing is configured to interface with an inner circumferential surface of the recess to provide the push fit connection wherein the outer circumferential surface of the second housing further comprises at least one first surface formation which is configured to interface with said inner circumferential surface of the recess. ### Claim 2 (depends on 1) The mouthpiece assembly according to claim 1, further comprising at least a first barrier that is porous to the flow of aerosol and which prevents material in the second housing from exiting the second housing. ### Claim 3 (depends on 2) The mouthpiece assembly according to claim 2, wherein the first barrier is arranged towards a first opening at a proximal end of the second housing. ### Claim 4 (depends on 3) The mouthpiece assembly according to claim 3, further comprising a second barrier that is porous to the flow of aerosol and which prevents material in the second housing from exiting the second housing, wherein the second barrier is arranged towards a second opening at a distal end of the second housing. ### Claim 5 (depends on 4) The mouthpiece assembly according to claim 4, wherein the second housing is a tube and the first opening is at the proximal end of the tube and the second opening is at the distal end of the tube. ### Claim 6 (depends on 4) The mouthpiece assembly according to claim 4, wherein the second barrier is a mesh. ### Claim 7 (depends on 2) The mouthpiece assembly according to claim 2, wherein the first barrier is a mesh. ### Claim 8 (depends on 1) The mouthpiece assembly according to claim 1, wherein the second housing comprises a first portion that is within the first housing and a second portion that extends out of the first housing and wherein the second portion is within the aerosol provision device when the mouthpiece assembly is connected to the section of the aerosol provision device. ### Claim 9 (depends on 1) The mouthpiece assembly according to claim 1, further comprising at least two first surface formations which are configured to interface with the inner surface of the section of the aerosol provision system. ### Claim 10 (depends on 1) The mouthpiece assembly according to claim 1, further comprising at least three first surface formations which are configured to interface with the inner surface of the section of the aerosol provision system. ### Claim 11 (depends on 1) The mouthpiece assembly according to claim 1, wherein at least one of the at least one first surface formations is a ridge that extends circumferentially around an outer surface of the second housing. ### Claim 12 (depends on 1) The mouthpiece assembly according to claim 1, wherein at least one of the at least one first surface formations is a ridge that extends longitudinally on an outer surface of the second housing. ### Claim 13 (depends on 1) The mouthpiece assembly according to claim 1, wherein at least one of the at least one first surface formations is configured to interact with a corresponding second surface formation on the inner surface of the section of the aerosol provision system. ### Claim 14 (depends on 13) The mouthpiece assembly according to claim 13, wherein the at least one of the first surface formations is a first ridge which is configured to interact with a corresponding second groove on the inner surface of the section of the aerosol provision system. ### Claim 15 (depends on 13) The mouthpiece assembly according to claim 13, wherein the at least one of the first surface formations is a second groove which is configured to interact with a corresponding second ridge on the inner surface of the section of the aerosol provision system. ### Claim 16 (depends on 1) The mouthpiece assembly according to claim 1, wherein the second housing comprises a protrusion against which a distal end of the first housing abuts. ### Claim 17 (depends on 1) The mouthpiece assembly according to claim 1, wherein the first housing comprises an aperture for the flow of aerosol to pass through for inhalation by the user and wherein the first housing is asymmetric about the aperture. ### Claim 18 (depends on 1) The mouthpiece assembly according to claim 1, wherein the first housing has a cross-sectional area at a distal end which is greater than cross-sectional area at a proximal end. ### Claim 19 (depends on 1) The mouthpiece assembly according to claim 1, wherein the first housing has a cross-sectional area at a distal end which is greater than a cross-sectional area of a proximal end of the second housing. ### Claim 20 (depends on 1) An aerosol provision device comprising a mouthpiece assembly according to claim 1 and a device body. ### Claim 21 (depends on 20) The aerosol provision device according to claim 20, wherein, when the mouthpiece assembly is connected to the device, at least a portion of the second housing is contained within the device. ### Claim 22 (depends on 20) The aerosol provision device according to claim 20, wherein the device further comprises a cartridge and wherein the mouthpiece assembly is releasably connected to the cartridge. ### Claim 23 A method of manufacturing a mouthpiece assembly for an aerosol provision device, the mouthpiece assembly comprising a first housing for being received, in use, in a mouth of a user, and a second housing for containing a material, arranged such that, in use, an aerosol generated by the aerosol provision device enters the mouthpiece assembly and flows through the material in the second housing to be flavored by the material before passing out of the mouthpiece assembly for inhalation by the user, wherein the first housing and the second housing are connected together to form the mouthpiece assembly and the mouthpiece assembly is configured to be releasably connectable to a section of the aerosol provision device from which the aerosol generated by the aerosol provision device enters the mouthpiece assembly, the method comprising: providing the first housing; providing the second
